Icinga on CentOS 6.4 via RPM

icinga-on-centos.sh

# These are very quick & dirty notes on getting Icinga installed on Centos 6.5 via RPMs,
# as most documentation seems to be based around source installation. It's mostly recovered from
# my history as I worked it out, so no guarantees are offered.

# Make EPEL available
sudo rpm -Uvh http://mirror.bytemark.co.uk/fedora/epel/6/i386/epel-release-6-8.noarch.rpm
 
# Install HTTPd
sudo yum install httpd
sudo service https start
sudo chkconfig httpd on
sudo iptables -I INPUT 1 -p tcp --dport 80 -j ACCEPT && sudo service iptables save
 
# Turn off selinux
echo 0 >/selinux/enforce
sed -i'' -e 's%^SELINUX=.*$%SELINUX=disabled%g' /etc/selinux/config
  
# Ensure Postfix will work
sudo mkfifo /var/spool/postfix/public/pickup
sudo service postfix restart
sudo chkconfig postfix on
  
# Install MySQL and repos
sudo yum install http://www.percona.com/downloads/percona-release/percona-release-0.0-1.x86_64.rpm
sudo yum install Percona-Server-server-56
sudo service mysql start
sudo chkconfig mysql on
